Out of Control

Its a "demand valve" and sits in the line between the cask outlet and pump inlet. Usually near the pump. But I guess you will be emptying this cask within a day so you don't actually need it provided you release all the pressure in the cask (the demand valve will prevent over-pressured beer pushing its way through the pump).

BTW. If people are serving themselves remove the sparkler from the pump nozzle. People don't understand sparklers and some and will attempt to spray beer into a glass.

EDIT: Another purpose of "demand valves" is to prevent worn-out pumps sucking beer back out of the glass. But the pump in the picture looks pretty new.

I guess you have a few things to think about. So get rid of one (the demand valve) and just take it off. Just connect the pump directly to the cask, but bear (EDIT: "bare", I'm always doin' that) in mind what I said about relieving any pressure in the cask or the beer will force itself out of the pump. If you've got a cask you've no doubt been given instructions on venting, soft spiles and all that.
